False
True. An indirect proof, also known as proof by contradiction, involves assuming that the statement to be proven is false. From this assumption, logical deductions are made, ultimately leading to a contradiction or an impossible situation, which implies that the original statement must be true. This method is often used in mathematical reasoning to establish the validity of a statement.
A postulate.
Assumption
True. In an indirect proof, also known as a proof by contradiction, you start by assuming that the opposite (or converse) of what you want to prove is true. Then, you logically derive a contradiction from that assumption, which shows that the original statement must be true.
Induction
Assuming the truth of something to be proved is known as beggining the proof using the assumptive method in logic. This method helps establish the validity of a statement by starting with the assumption that it is true and then deriving logical consequences from that assumption. However, it is important to later verify that the assumption leads to a valid conclusion through rigorous proof.

TrueIt is true that the body of an indirect proof you must show that the assumption leads to a contradiction. In math a proof is a deductive argument for a mathematical statement.

Theoretical assumption is the first step of the scientific method of proof, cause and effect. Your observations allow you to make assumptions and collecting empirical data can give you the proof. Thereby changing your theorem to accepted fact, practical data.
Identify the conjecture to be proven.Assume the opposite of the conclusion is true.Use direct reasoning to show that the assumption leads to a contradiction.Conclude that the assumption is false and hence that the original conjecture must be true.
